REASSEMBLY SERVICE POINTS
>>A<< SPACER/SIDE
GEAR/WASHER/PINION/PINION SHAFT
INSTALLATION
1. Install the spacer on the back of each side gear,
then install the side gears into the differential
case.
NOTE: Use spacers of a medium thickness (0.93
−
1.00 mm) when installing new side gears.
2. Attach the washer to the back of each pinion,
make both pinions engage with the side gears
simultaneously, and bring the pinions into position
while turning the gear set.
3. Insert the pinion shaft.
4. Measure the backlash between the side gears
and pinions.
Standard value: 0.025
− 0.150 mm
5. If the backlash is not within the standard value
range, replace the spacers with appropriately
selected ones and measure the backlash again.
NOTE: The amount of the backlash must be the
same on both side gears.
>>B<<LOCK PIN INSTALLATION
Orient the lock pin as shown in the drawing.
